The DS1391U-33+ is a low-voltage serial-peripheral interface (SPI) real-time clock (RTC) from Analog Devices / Maxim Integrated. This IC provides accurate timekeeping, including hundredths of seconds, seconds, minutes, hours, day, date, month, and year information, with automatic leap-year compensation valid up to 2100. It supports both 12-hour and 24-hour formats with an AM/PM indicator.
Key features include a programmable time-of-day alarm, power-fail detect and switch circuitry, and trickle-charge capability. The DS1391U-33+ is designed for a wide operating voltage range of 1.3V to 5.5V and operates within an industrial temperature range of -40°C to +85°C. It communicates via an SPI-compatible interface and is available in a 10-pin µSOP package, suitable for surface mounting.
This RTC is ideal for applications requiring precise timekeeping, such as hand-held devices, GPS/telematics systems, embedded time stamping, and medical devices. The device also offers a reset output/debounced input pin.
